11. Repeat the entire procedure using hot tap water instead of cold water.

What
do you see happening inside the jar?

Water
vapor is created as water heats under the lamp. Swirling the water also
help water molecules to move into the air from the waters surface.

When you pull the glove out of the jar, the air pressure is lowered inside the jar. The jar contains the same number of air molecules, but they have more space between them (they are less dense). Molecules collide with each other less frequently and slow down, causing the air temperature to go down.

When you press the rubber glove into the jar, you are increasing the air pressure. The air becomes more dense as the molecules are crowded together. This also causes the air to heat up as molecules collide with each other more often.

The smoke particles provide tiny nuclei on which water vapor molecules condense, when the air temperature cools. This forms a little cloud.

There must be three main ingredients present in order for clouds to form:

 Moisture - There must be sufficient water vapor in the air to build a cloud.

 Cooling air - The air temperature must decrease enough for water vapor to condense.

 Condensation nuclei - Tiny particles, invisible to the human eye, such as dust, dirt, and pollutants, provide surfaces on which water molecules can gather and condense into water droplets.
